“…On the other hand, up to 31% of clutch losses on the waterlogged sedges were due to predation, and only 2% of nests sank into the water (Golawski et al 2016b). But such flooding occurs just once every few years, so in the intervening years these terns nest on the largest ox-bow lakes of rivers (Golawski et al 2015). Being an expansive species, CHL does not occupy the same niche (habitat) in the invaded environment as in the native one and sustains substantial brood losses under appropriate weather conditions.…”

“…Being an expansive species, CHL does not occupy the same niche (habitat) in the invaded environment as in the native one and sustains substantial brood losses under appropriate weather conditions. CHN should be able to cope with inclement weather conditions far better, as it turns up very early, anticipating, as it were, the advent of the strongest winds in the breeding season; ox-bow lakes are still CHN's basic breeding habitat in east-central Poland (Golawski et al 2015). This shows that a species nesting there for many years has higher hatching success (treated as gauge productivity, Mazzocchi et al 1997) in comparison with species in expansion at the edge of breeding range.…”

“…1; Tomiałojć and Stawarczyk 2003). The Bug is one of the largest rivers in Poland protected within the Natura 2000 network, with abundant breeding sites like ox-bow lakes (Golawski et al 2015). All the oxbow lakes investigated supported a similar vegetation-mostly Water Soldier, White and Yellow Water Lilies Nymphaea alba and Nuphar lutea and Frogbit Hydrocharis morsus-ranae.…”

“…The typical nesting habitat of CHL is assumed to be naturally waterlogged grassland (Kapocsy 1979;Cramp 1985), but in dry seasons in east-central Poland this species has occurred on ox-bow lakes (Dombrowski et al 2014). During the high water period, CHL in east-central Poland (study area) located their colonies in waterlogged sedge fields three times more often than CHN did, while the latter nested three times more frequently on ox-bow lakes (Golawski et al 2015). The range of CHL in Europe originally covered the eastern part of the continent, with isolated sites in NE Poland, Hungary and Romania (Cramp 1985).…”

Identifying the key factors governing the expansion of a species' range is difficult because of the multiple interactions of environmental and biological factors. Among the biological factors are breeding parameters, which at the edge of a species' range may indicate the traits involved in limiting species distribution. To evaluate whether the hatching success of two sympatric species of terns was dependent on weather parameters, a study was carried out in the valley of the River Bug in eastern Poland. During 2007-2010, nine colonies with 113 clutches of Whitewinged Tern (CHL, an expansive species, new to the region since 1997) and 92 clutches of Black Tern (CHN, a non-expansive species, nesting in stable numbers in this region for many years) were monitored. CHN arrived on average 9 days earlier than CHL. While CHN arrived in east-central Poland earlier and earlier during the 1998-2013 period, no such trend was recorded for CHL. The clutch initiation median in CHL was 8 days later than in CHN. The hatching success of CHL was statistically less than that of CHN (41.6 vs. 69.6%). A general discriminant analysis model showed that successful CHL clutches depended on the maximum daytime wind speed (strong winds can be disastrous for breeding terns), colony identity and clutch initiation date. In the case of CHN, none of these factors had a statistically significant influence on hatching success, although the clutch initiation date was very close to being significant. These results suggest that a species which nested in the same location for a long time in relation to ambient weather conditions has higher hatching success than the one which is in the process of expanding its distribution range.

“…CHL is thus still a species expanding westwards, with peripheral breeding populations in eastern Poland. The typical nesting habitat of CHL is naturally waterlogged grassland (Kapocsy, 1979;Cramp, 1985;Golawski et al, 2015), but in dry seasons in eastern Poland this species has been found on oxbow lakes-permanent water bodies with floating vegetation offering potential nesting sites for terns, mainly Water Soldier (Stratiotes aloides Linnaeus, 1758) (Golawski et al, 2015). A number of differences have been found in some breeding parameters like hatching success between waterlogged grassland and oxbow lakes in Poland (Golawski et al, 2016a).…”

Nests should be built on sites that provide optimal conditions for reproduction, so nest site characteristics are assumed to have an adaptive value. In this paper, we compared the hatching success of two species of terns: Black Tern (Chlidonias niger) (a nonexpanding species) and White-winged Tern (Chlidonias leucopterus) (an expanding species, new to the region since 1997) with respect to microhabitat nest characteristics on oxbow lakes in eastern Poland. The hatching success of White-winged Tern was lower than that of Black Tern (41.7 vs. 66.7%). Comparison of habitat parameters at the nesting sites between the two tern species showed a significantly greater depth of water and distance from helophytes in Whitewinged Tern. Successfully hatched White-winged Tern clutches were situated much closer to the helophytes and were initiated on average up to 8 days earlier than clutches that failed to hatch. In Black Tern, hatching success was not influenced by environmental factors describing nest location. In eastern Poland, oxbow lakes are probably a suboptimal habitat and constitute an ''ecological trap'' for White-winged Tern; because of these suboptimal habitats, the expansion of this species may be quite slow in predominantly dry years in eastern Poland.

Vector-transmitted haemosporidians are among the most common parasites in birds, but our knowledge of the inter-specific patterns of infection rates and the parasite community composition is far from complete because of the unequal distribution of the screening effort across bird families and genera. To assess infection rates and the diversity of haemosporidians from the genera Plasmodium, Haemoproteus, and Leucocytozoon in marsh terns, which represent poorly explored in this regard genus of the family gulls, terns, and skimmers (Laridae), we screened two species: the Whiskered Tern (Chlidonias hybrida) and the Black Tern (Chlidonias niger). We sampled these long-distance migratory birds on breeding grounds: the Whiskered Tern in south-central Poland and north-central Ukraine, and the Black Tern—in north-central Ukraine. We found that birds from both species were infected only sporadically, with prevalence at the population level not exceeding 3.4%. Only parasites from the genera Plasmodium and Leucocytozoon were detected. There was neither an inter-specific difference nor a difference between populations of the Whiskered Tern in infection rates. In total, we registered three lineages—one Plasmodium and two Leucocytozoon—that were previously recorded in other bird species, and two unidentified Plasmodium infections. One of the lineages (Leucocytozoon LARCAC02) represents a specialist parasite with the host range restricted to larids and geographic range restricted to Poland, and two others (Plasmodium SGS1 and Leucocytozoon CIAE02) represent generalist parasites with very broad host and geographic ranges. This study reinforces the existing evidence that terns host parasites from genera Haemoproteus, Plasmodium, and Leucocytozoon only sporadically.
